What your building permit file contains
A building permit is far more than a single drawing. The regulatory file we assemble brings together the site location plan, the block plan dimensioned in three dimensions, the elevations and roof plan, the site cross section, the notice describing the land and the project, and the integration documents: a graphic document and photographs that place the building in its immediate and wider surroundings.
Every item is numbered and completed on the Cerfa form matching your project. This attention to formalities avoids missing documents, the leading cause of a longer review, and hands the planning department a file it can process straight away.
Up to 150 m²: your project without a mandatory referral
For a detached house or an extension that keeps the total floor area below the 150 m² threshold, French law lets you entrust the design of your drawings and the filing of your permit to a building designer. ArchiMade designs the whole file, checks that it matches the local town planning rules (PLU) of your commune, then files it for you.
Above 150 m², using a professional entered on the French national roll becomes compulsory. We tell you clearly and early: that threshold is a legal boundary we respect, never a hidden restriction.
Review times and follow up at the town hall
The review period for a building permit for a detached house is generally two months from the filing date, and it can be extended if your land sits within the perimeter of a listed monument or a protected zone. We prepare the file to limit requests for additional documents and stay available throughout the review to answer the planning department.
Once the consent is granted, you hold technical drawings your builders can use directly, with no extra tidying up stage. If the project changes after approval, we also prepare the amending permits you need.
